flavor wick question for kanger mini protank 2

I just bought these to use as replacement flavor wicks that I can cut to size and stick on top of my coil wick. I lost my flavor wicks so had to improvise and buy these since the vape shop i was at didn't have replacement wicks alone.

does anyone know if these are what I should be using as flavor wicks? how long till they vape consistently? I had maybe 20 puffs with the newly improvised flavor wick and some hits are bigger than others, so just hoping I did it right because I want a consistent vape cloud
